Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth operation with its refined 1:18 gear ratio. Continuing the legacy of the original 1966 closed-housing design, this updated iteration features CNC-machined components with a self-locking drive mechanism to ensure sensitive, uniform, and stable tuning performance.
Crafted with premium brass string posts precision-fitted directly into the housing, the M6 135 provides exceptional wear resistance and tuning stability. Each enclosed tuner is permanently lubricated with specialized grease for completely maintenance-free longevity across diverse playing environments.
Featuring the innovative stepped flanged washer, it centers the string post securely through the threaded bushing without requiring stepped headstock drilling. This design eliminates tilting torque and reduces strain on both the post and rear mounting screws, matching the exact mounting dimensions of its predecessor for effortless retrofitting.
